[ClusterLabs] Pacemaker/pcs & DRBD not demoting secondary node to Slave (always Stopped)

Thank you for comment.  I attempted to use iDRAC/IPMI STONITH, and after
spending over a day, I had to put it on the backburner for timeline
reasons.  For whatever reason, I could not get IPMI to talk, and the
iDRAC5 plugin was not working either for reasons I don't understand.

Is that what you had in mind, or is there another method/configuration for
fencing DRBD?

Thank you for your advice,

Jason
